Arthritic overweight Samoyed: what actually helps

Most arthritis products for dogs are either underdosed or poorly matched to the dog's specific situation — size, age, and severity all change what works. An older, heavier dog like a Samoyed is a really particular case, because the extra weight is actively worsening the joint load at the same time the joints are degenerating. What are you noticing — is he stiff getting up in the morning, hesitant on stairs, or has his walk pace just dropped off? And roughly how much does he weigh at the moment?

Poor Polar — that picture is really clear, and honestly it's a combination I see a lot in older northern breeds. The 6kg of extra weight is doing real damage here: every kilo over ideal puts roughly 4–5 times that force through his joints on each step. So before any supplement can do its best work, the weight has to start coming down. That doesn't mean dramatic restriction — just switching to a proper joint-and-weight-management food and reducing treats to near zero makes a meaningful difference within 8–12 weeks. Is he on a standard adult food right now, or something breed or age specific?

That's the problem — the supplement market for dogs is swamped with low-dose products that look impressive on the label but don't actually hit therapeutic levels. For a 32kg dog with visible symptoms, you need a high-strength formulation, not a standard one. My clear recommendation for Polar is YuMOVE PLUS for Large Dogs. It's a step above their standard YuMOVE — it has a meaningfully higher dose of ActivEase green-lipped mussel, which is the ingredient with the best evidence behind it for joint mobility and inflammation in dogs, plus glucosamine and chondroitin at levels that actually matter for a dog his size. It comes as a chewable tablet, most large dogs take it easily. You'd give two tablets daily for the first 6 weeks as a loading dose, then drop to one. It's widely available on Amazon UK and is one of the few products where you're genuinely getting a dose matched to the dog's weight.

Do both at once — there's no benefit in waiting. For food, look at Hill's Prescription Diet j/d or Royal Canin Joint Care if your vet will sign off, or if you want an over-the-counter option, Hill's Science Plan Light Large Adult is a solid starting point for managed weight loss without needing a prescription. Transition the food gradually over 7–10 days to avoid stomach upset. The supplement and the food change work on different mechanisms, so starting them together means Polar gets the benefit sooner. Keep his walks short and low-impact for now — 10 minutes twice a day on flat ground is better than one longer walk that wipes him out. You should see some improvement in morning stiffness within 4–6 weeks of the YuMOVE PLUS loading dose.

Two practical things that make a real difference: get him an orthopaedic memory foam bed if he doesn't already have one — lying on a hard surface significantly worsens joint stiffness overnight in older dogs. And if the stairs are now a barrier, a ramp or set of dog steps for any furniture he still uses is worth it. Hydrotherapy is genuinely excellent for dogs like Polar if there's a facility near you — it builds muscle around the joints without impact loading. Beyond that, the YuMOVE PLUS and the weight work are your two highest-leverage moves. Reassess in 8 weeks — if he's not meaningfully better, that's a conversation for your vet about prescription anti-inflammatories.
